Guido Casati da6b1a4be4 Fixes to SI message struct item in CU messages 
* num_SI is the size of the list of gNB-CU System Information messages
* the new struct member is an array, sized after the maximum nb
  of SIB types, which contains the SI container, the container length
  and the SIB type

Robert Schmidt 956df365de Refactor F1 Setup Req/DU config update: transport slices via F1 and read config 
In the DU, read slice information from the DU config file. Handle
multiple slices within the F1 Setup Request structure representation,
and forward it via F1 to CU. The DU slice information is stored in the
setup request structure.

Giulio CarotaandRobert Schmidt 20710c9a91 Implement F1AP RRC Version encoding/decoding in CU&DU 
RRC Version is a required IE. Hence, implement the encoder and decoder
for this message. At the DU and CU, read the RRC Version we use and fill
the corresponding field.

Robert Schmidt 4c2bfe7a1f F1AP: send() functions take assoc_id 
To allow to send F1 messages to multiple DUs from the CU, we need to
send these messages via different assoc_id (SCTP association ID,
basically akin to a file descriptor). Currently, the assoc_id is stored
in a context at the F1 module and retrieved in
f1ap_itti_send_sctp_data_req().

To facilitate a later change towards indicating (from the RRC) to which
assoc_id (hence, DU) to send a message, we refactor all
CU_send_*()/DU_send_*() functions to take the assoc_id as a parameter to
which to send messages. In this commit, we then pass the assoc_id from
the context. A later commit changes this (at the CU) to pass the
assoc_id from the message to be sent.

Robert Schmidt 57876fc13f F1 setup request: message encoder takes struct 
Instead of storing the F1 Setup Request implicitly in F1 context, we
provide the F1 Setup Request message to be encoded explicitly to the
encoding function.

Robert Schmidt 48f82a63aa F1: do not assert on unknown F1 message 
Previously, in f1ap_decoder.c, we asserted if we did not know a message.
Apart form decoding, we did not do anything in that file.

Additionally, in f1ap_handlers.c, we were also checking for an unknown
message, and printing a warning if a handler is not known.

This commit moves the F1AP message decoding to f1ap_handlers.c, and
deletes f1ap_decoder.c. In summary, we don't assert on an unknown
message, and compile less files. The rest is unchanged.
